that y"the gasv or pressure fluid received through vthe outlet 18 will enter the chamber and Iany excessjof pressure within the outlet 3, will cause the elevation of the bell 21 and through the linkvll the elevation'of the outerend of the lever 11, this elevation of the outer end will cause the depression of the inner end and will cause the lowering f ofthe valves 4 into closing or closed position, thusregulating theow of the gas or pressure iuid `romthe'linlet through the outlet of the casing. By this means the gas or pressure fluid within" the bell 21 above the liquid level'of the receptacle 19', will form a resilient cushion to lend a slow and e steady movement to the lever 11, instead of a jerky movement, as is caused by the quick lntroduction'of` an overcharge` against the diaphragm 8,v and the consequent quick re-` t lease `due to the seating of thevalves 4. e v 1 'e Ithas-been found 4in practice, that with "the present attachmentconnected to a pres-` sureiregulating valve of this character, that vpractically "no lvariation in thefpressure ofv the gas Aor pressure iuidppasslng. through the outlet 3 1s noticeable, an indicating de-y vice controlled by suchk pressure .having vshown that for, a period of vtwenty-four ,y that thev conduit 15 be lconnected beyond the outlet endroit' the/valve, so asI t0 be affected by thereduced pressure insteadofnthe pres sure before passing through thervalve :By
